When you said radio I am thinking you mean receiver when you say stereo. Have you tried using your CD into the input that you are plugging your mixer into? If you get both sides , right and left of your CD then it is a problem with the signal from the mixer and we can work from there.

This is a wild educated guess.

I repaired a Behringer guitar amp that had a DSP effects in it (BX1200 I believe).

The effects were on a seperate board and the board had its own 5 volt power supply. The filter capacitor for the 5 volt power on the board was UNDERSIZED and it had degraded causing the 5 volts to drop out of regulation, dipping to 4 volts. This caused the DSP effects to fail.

YOUR device MAY use the same DSP OR design.

Check the 5 volt power with an OSCILLOSCOPE to look for dips below the 5 volt operating point that occur at 120 HZ.

After reviewing the schematic, I don't understand how the Phantom power can REMAIN on with the power switch off... this CANNOT occur except for what energy is left in the 48 volt supply filter cap... This might last for minutes after the fuse went... UNLESS you have devices connected which are backfeeding the 48 volts. (which would be a disaster)

The 48 volts, +/- 12 volts and +/- 15 volts and the +5 volts ALL come from the SAME switching power supply. I suspect one of the filter caps went or the primary switching regulator a TDP245Y chip.

You should ONLY work on the line side of this using an ISOLATION transformer since the line side has lethal voltages.

To do testing, one replaces the fuse and puts a 60 Watt light bulb in series with the hot side of the inout line. The lamp "acts" as a resetable fuse and limits the current for testing. When all is well again, the lamp will remain out with the power flowing through it.

The D1 diode bridge and C7 input rectifier and filter are first things to check. You can do those with an ohmmeter.

I will caution you to ALWAYS power any and all equipment from the SAME power source. Plugging in devices from across the room will set up ground loops and any ground fault will fry equipment.

Without knowing how you have your monitors configured it is hard to analyze what you have posted.

In brief, SW3 on the schematic that selects MAIN L and MAIN R in the upper position, MAIN and MONITOR in the middle, and bridged in the lower is used to configure the internal amps.

In the upper position, the amp power outputs come from the mixed stereo bus and are simultaneously controlled as a stereo signal by the MAIN slider.

In the middle position MAIN and MONITOR, the left amp receives the signal from the mix bus and is controlled by the MAIN slider. The MONITOR output from the other side of the power amp is controlled ONLY by possibly the "MONO" slider.

The schematics are hard to decode and what is needed is a signal flow diagram.

For my uses, I don't try to use splitting the power amps between mains and monitor but prefer to use the mains together with SW3 in the upper position (Note your 27 may be refering to the user manual designation for same switch). I then use another small amp from the 1/4 inch MONITOR jacks whcih are under control of the MONITOR sliders.
Please note that the MIX for these two MONITOR channels is controlled by the MON1 and MON2 knobs for each channel.
